Creator:: McGregor, Mark D., Oakes, Robert D., Meyer, Hubert E., and United States. Forest Service. Northern Region
Abstract:: A granular controlled release formulation of 2 percent MCH was applied at 4.48 kg/ha to 76.9 ha of uninfested, windthrown Douglas-fir by helicopter with a modified aerial spreader of 1.12 m capacity in May 1982. Douglas-fir beetle population reduction was 96.4 percent by late June. With one exception, treated plots...
